Document Summary
Imagine that you were a research assistant in the laboratory that was planning to carry out the revised design to further examine advantages of video-based software instruction . Assignment to conditions#1: one approach is to flip a coin for each participant using say heads = instruction manual & tails = instructional video. Assignment #1: for statistical reasons it is convenient that we have =n . That is, the same number of participants in each condition of the between groups research design. However this doesn"t always happen when this approach is used: how many folks in the lab got =n when they used this approach, what might improve the chances of getting =n when using this approach? . This is generally known as a randomized block procedure a block is one participant in each treatment condition. Apply this approach below putting manual or video beside each participants name under.
